稀土对CSP低碳钢再结晶组织的影响

Effect of Rare Earth on Recrystallization Microstructure of CSP Low Carbon Steel

近年来,稀土元素对钢的再结晶作用已有很多报道。然而,其作用机理尚存在争议。本文利用热处理炉及金相显微镜,研究了稀土对CSP低碳钢冷轧薄板退火过程中组织的变化规律,探寻稀土在低碳钢中的作用机理。

In recent years,there have been many reports on the recrystallization effect of rare earth elements on steel.However,the mechanism of its action is still controversial.In this paper,the effect of rare earth on the microstructure of cold rolled CSP low carbon steel sheet during annealing is studied by means of heat treatment furnace and metallographic microscope,and the mechanism of action of rare earth on low carbon steel is explored.
